Data Acquisition Interface (9062)
The Data Acquisition Interface (DAI) consists of isolation and data acquisition units.
The isolation unit converts high-level voltages and currents found in electric power systems and power electronics circuits into low-level signals, and routes these signals to the data acquisition unit. The data acquisition unit converts the low-level signals into digital numbers (data) that are sent to the personal computer that runs the LVDAM-EMS software.
The DAI module has isolated voltage and current inputs fitted with 4-mm banana safety jacks, which can be connected to AC or DC power circuits. Low-level inputs for torque and speed measurement can be connected to the Prime Mover/Dynamometer, Model 8960, which provides output signals proportional to torque and speed.
Eight software-programmable, low-level, auxiliary analog inputs allow measurement of additional circuit parameters. Two analog outputs, also software-programmable, allow direct control of the Prime Mover/Dynamometer, or of the Power Electronics modules to which they are connected. All inputs and outputs are protected against wrong connections and overvoltage/overcurrent conditions.
